Simple and easy to use collimation cap, saves making your own and this comes with very good reflective underside to make collimation alignment easy in mirrors. I use this for very quick check before each viewing session -

I'm new to astronomy so finding out that my newtonian needed collimating at first frightened me, so after much research I discovered a laser collimator and paid a small fortune for it and it just complicated maters, so looking for a simpler answer to collimation I came across the Rigel Aline and was surprised on exactly how simple it was to use and the results were fantastic and at a tenth of the cost of the laser.
I couldn't recommend the Rigel Aline enough

i lived in fear of collimation , then i bought a collimation cap, so straight forward to use, i highly recommend this cap.

I have a premium Premium Cheshire also, but this thing is actually better at a 6th of the price for quick collimation. I use it on a Sky-watcher 200p Dob, and all that is required (once you have your secondary square) is to point it at some blue sky and make sure the cycles are concentric.
Love it!

I haven't used this yet as the secondary on my scope is still aligned (the primary is non-collimatable) - but in terms of price and delivery then FLO have once again been unbeatable.

Brought this with my new 130pds skywatcher it works wonders keeping both secondary and primary mirrors aligned. The scope was well collimated as you would expect from FLO but while in use and transporting the gear it affects the alignment of the mirrors this is a must a great tool to use.

Being new to telescopes, I was worried about collimation on reflector dobsonians. This cap that came with instructions was easy to use and adjust. My new scope was slightly out of collimation and this cap sorted it. Took less than 1 minute!

Arrived within 48 hours of ordering. The cap comes with instructions to help collimating but it’s a very simple premise. Would appear my scope is still perfectly collimated (which was bought from FLO in April).

Good quality! Will be the first time ever for me using this in combination with the premium Cheshire from FLO. 👍🏻

Brought this to use alongside the premium Cheshire and it works brilliantly, great service again from FLO thanks guys
